Withholding Tax Filing

A limited company's financial statements must be audited and opined on by a CPA registered with the Federation of Accounting Professions, approved at an annual general meeting held within four months of the year end, and submitted to the DBD via DBD e-Filing within one month of that approval. A practical order is: confirm the accounting period and which taxes apply, collect source documents (tax invoices, receipts, payslips), reconcile against bank records, then file and keep the filing evidence. Watch out: failing to hold the AGM on time or to submit financial statements carries fines for both the company and its directors. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on document volume and scope — ask our team by phone, LINE or email. Withholding tax requires a withholding certificate for every payee, remitted with form P.N.D.3 or P.N.D.53 depending on the payee type, by the statutory date in the following month. Verify forms and deadlines with the Revenue Department (rd.go.th) and financial-statement requirements with the Department of Business Development (dbd.go.th).

Late filing or underpayment attracts a surcharge of 1.5% per month of the tax due under the Revenue Code, plus penalties depending on the return type, while failure to submit financial statements to the DBD carries fines under the Accounting Act. Keep each document paired with its ledger entry and check that the tax ID and registered name match on every page. Watch out: a tax invoice missing any particular required by the Revenue Code can cost you the input VAT credit. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on document volume and scope — ask our team by phone, LINE or email. VAT-registered operators file form P.P.30 monthly and maintain input/output tax reports that agree with the tax invoices issued and received in that month. Caution: accounting source documents must be retained for the statutory period — destroying them early leaves you without evidence in a retrospective audit. Verify forms and deadlines with the Revenue Department (rd.go.th) and financial-statement requirements with the Department of Business Development (dbd.go.th).

A person present in Thailand for 180 days or more in a tax year is a tax resident; under Revenue Departmental Instructions Paw.161/2566 and Paw.162/2566, foreign-sourced income brought into Thailand from tax year 2024 onward is assessable, subject to relief under the applicable double tax agreement. If a loan, licence renewal or visa application depends on the figures, allow lead time to close the books and obtain certified copies. Watch out: failing to hold the AGM on time or to submit financial statements carries fines for both the company and its directors. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

The payer must withhold tax according to the type of income, issue the withholding certificate (form 50 Tavi) to the payee and remit it on PND.3 (individual payees) or PND.53 (juristic payees) by the 7th of the following month, with an extension when filing electronically. A practical order is: confirm the accounting period and which taxes apply, collect source documents (tax invoices, receipts, payslips), reconcile against bank records, then file and keep the filing evidence.

Personal income tax is filed on PND.90 or PND.91 by 31 March of the following year — online filing receives an extension announced by the Revenue Department — and certain income types also require the half-year PND.94 return. A practical order is: confirm the accounting period and which taxes apply, collect source documents (tax invoices, receipts, payslips), reconcile against bank records, then file and keep the filing evidence. Watch out: expenses without documentation identifying the recipient are commonly added back as non-deductible for corporate income tax. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

Accounting, tax, property and estate work for foreign nationals is run jointly with our auditors and lawyers so the translated file and the filed file always match. One coordinator owns the matter end to end and reports progress by LINE or email at the intervals you set. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com. Send scans of every page for review before sending originals; that is when faded seals, passport-spelling mismatches and expired documents can still be corrected. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. Keep a digital copy of the finished certified set so it can be referenced if the destination asks for additional documents or a re-filing.

Tell us where the document will be used and you will get a plan and a price the same business day. Send scans of every page for review before sending originals; that is when faded seals, passport-spelling mismatches and expired documents can still be corrected. Caution: each certification covers only what its own stamp states; it does not make a document automatically acceptable everywhere. Confirm the receiving authority's conditions case by case. The workable order is: check that the source document is complete and legible, translate it, certify the translation, file for legalisation with the Department of Consular Affairs, then obtain the destination embassy's certification — or an Apostille where the destination is a convention party. Caution: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification.
